updated test code to DMD-1.007

# import std.stdio;
# 
# void printGC(){
#    GCStats stat;
# 
#    getStats(stat);
# 
#    writefln("poolsize: %s; usedsize: %s; freeblocks: %s; "
#       "freelistsize: %s; pageblocks: %s\n",
#       stat.poolsize, stat.usedsize, stat.freeblocks, 
#       stat.freelistsize, stat.pageblocks);
# }
# 
# int main(){
#    printGC();
# 
#    size_t len = 256 * 1024 * 1024;
#    byte* b = (new byte[len]).ptr;
# 
#    writefln("after allocating %s bytes", len);
#    printGC();
# 
#    delete b;
#    b = null;
